Introduction to Sample Preparation

Professor Nicholas Snow
Sample preparation is the most important, yet often most neglected area of chromatographic training and method development. The world's finest gas and liquid chromatographs generally cannot overcome mistakes made prior to sample injection.

This webinar will focus on general principles of sampling and sample preparation for chromatography and an overview of key concepts for several major sample preparation techniques, including:

* Liquid-liquid and liquid-solid extractions (LLE and LSE)
* Static headspace extraction (SHE)
* Solid phase extraction (SPE)
* Sorptive micro-extractions (SPME and SBSE).

Discussion will directed toward seeing the commonalities among all extraction techniques and toward choosing the best technique for a given analytical problem. Fundamentals of sample and glassware handling will also be reviewed.

This webinar is directed toward analysts who use these techniques hands-on every day and to the laboratory managers who must teach, train and supervise them.

  • Regardless of the colour of the next UK government that emerges as a result of the May election, the £30-£50bn NHS budget chasm is the abyss that all the parties fear in respect of its thereat to quality health service delivery and re-election.

    With political backs to the abyss, no hostages will be taken. It is not unrealistic to expect a well co-ordinated and concerted offence by politicians and patient organisations alike on industry pricing of innovative speciality and rare diseases medicines:

    With this scenario in mind pharmaphorum is once again working with IMS Health to bring you expert insight into what this means for the UK health system and more specifically market access for specialist treatments in the post-election environment.

    Angela McFarlane, Senior principal IMS Health Local Market Access, Anthony Grosso, Principal Pharmacist at the National Hospital for Neurology and Neurosurgery and Sheela Upadhyaya, previously a NHS Senior Manager with over 17 years of experience in the delivery of services and in commissioning of highly specialised services for rare and ultra rare conditions, combine with pharmaphorum's Paul Tunnah to deliver an accurate analysis and frontline insight as to the already complex roadmap for access is about to change again.

    This one hour event will include analysis of informed predictions which include:

    The NICE HTA criteria will get tougher post end to end review (IMMTreV)
    NICE and the NHS England will join forces to streamline access pre/post NICE
    Risk at local level will be shifted to Providers under the new marginal tariff arrangements; which could indeed see a close to the CDF as the PbR excluded drugs list becomes a thing of a glorious past
    Provider baselines will take the strain of innovation - the tough decisions will be softened by a drive to really accelerate uptake of NICE approved medicines

    How can industry prepare for these changes in what is already a tough and complex environment?

  • This session provides a local Trust perspective on how the Industry Costing Template can be practically embedded for financial management of commercial research studies.

    A brief overview of the national tool principles is provided, but the main focus of the session is on practical examples of how these principles have been locally developed and implemented to support investigator and directorate incentivisation to encourage involvement in commercial contract studies.

    Who should view this session?

    "Financial Management of Commercial Contract Studies: A Trust perspective" is a must see for all NHS staff supporting commercial research including R&D and Finance teams, as well as Local Clinical Research Network staff supporting Trusts in their area to conduct commercial contract research.
  • As part of the Network's HSJ award category sponsorship, Danetre Medical Practice were highly commended for the entry to Clinical Research Impact.

    Jo Gilford, Practice managing partner, and Laura Hopwood, research nurse, discuss their story and how the practice turned research into core business.

    The presentation covers:

    * Their vision for research in the practice
    * Actions and best practice in creating a research culture
    * Outcomes - how the research portfolio has increased by 500% to date since undertaking these actions
  • Biological terror agents are frequently spore-forming bacteria and hardy in the environment, intended to persist despite best efforts at disinfection. This webinar explores the field of UV-C disinfection and the power of pulsed-xenon UV disinfection systems to neutralize such threats. Full spectrum pulsed-xenon UV is lab-tested to deactivate bioterrorism agents in the environment, expanding the options for protecting first responders and armed forces from dangerous pathogens.
  • COPD is a widespread, costly and largely preventable condition which affects over 300 million people worldwide and is recognised as the ‘third-leading’ cause of death in most countries. Adherence rates among patients with the condition are seen to be low, despite evidence that shows appropriate use of medication and sensible lifestyle changes can reduce mortality by 60% and hospital admissions by as much as 42%.

    Given the proven increase in quality of life when adherence occurs, and yet the persistence of non-adherence globally, there is clearly a disconnect. So why is poor self-management so prevalent and what can we do about it?

    In conjunction with self-management and behavioural change specialists Atlantis Healthcare, we present a multi-stakeholder webinar and debate, which will combine real world patient needs with expertise from healthcare, pharma and patient advocates to look at the challenges to successful self-management/adherence and ascertain what the industry can do to better support patients in achieving optimum outcomes.

    The webinar is comprised of 15 minutes of presentation and 40 minutes of live debate - which you can participate in, sending questions to the panel.

    A live tweetchat (#rwCOPD) will follow the webinar, enabling full interaction across all stakeholders to further delve into this topic and explore some of the issues and solutions raised during the webcast.

    This is the second webinar within the Patient Insights Summarized series.

    Your panel for this event is:

    Ana-maria Arboleda, Managing Director, Atlantis Healthcare Spain
    Dr Joan Escarrabill, Director of the Master Plan for Respiratory Diseases, Ministry of Health (Catalonia)
    Prof. John Weinman, Head of Health Psychology, Atlantis Healthcare
    Rolf Taylor, ‎Senior Director, Corporate Development, COPD Foundation
    Paul Tunnah (Moderator), CEO, pharmaphorum

    "Getting the best from the Network" is a must see for any CRA, Start up manager, study manager or NHS R&D manager who is involved in setting up and managing commercial contract clinical research in the NHS.
  • The truth about delivering clinical research in the UK

    - Are you looking to deliver your research within Europe?
    - Need multiple, reliable sites?
    - Do you want to know why you should come to the UK?

    In the past the UK’s reputation for delivering clinical research was questionable. But that’s all changed. Over the last six years the research landscape here has changed dramatically allowing us to make great strides in delivering research for the life-sciences industry. So whether you’re a small CRO, a medium med tech, or a pharma giant - we can help you.

    The National Institute for Health Research (NIHR) Clinical Research Network* (see below) is hosting a live webinar which will explode common myths around the UK’s ability to deliver commercial clinical research. This session will be hosted by Matt Cooper, Life-sciences Development Director. It will include performance data that will demonstrate why the UK should be your first choice for clinical research. You can find out:

    - How much the UK’s market volume of commercial contract research (supported by the NIHR CRN) has changed
    - What percentage of the UK’s National Health Service (NHS) is actively delivering commercial contract research studies (with support from the NIHR CRN)
    - On average how many days it takes for NHS sites to get regulatory approval for research to take place (with NIHR CRN support)
    - What percentage of commercial contract studies (supported by the NIHR CRN) are delivered to time and target
    - How we are keeping clinical research in the public eye
    - How the UK is sharpening its competitive edge by achieving more and more key first global patient milestones

  • Sports Drug Testing: Chromatography & Mass Spec-Based Approaches Recorded: Sep 9 2010 51 mins
    Professor Mario Thevis
    Doping control analysis predominantly utilises chromatography and mass spectrometry-based approaches to detect prohibited substances and methods of doping. These compounds and methods present both low and high molecular weight analytes of xenobiotic or natural / endogenous origin, which are to be detected, and occasionally quantified, using state-of-the-art instruments.

    The majority of the employed tools provides low resolving power. However, high resolution / high accuracy mass spectrometry has gained much attention recently due to: constantly increasing analytical requirements concerning the number of target compounds; the complexity of analytes (e.g. peptides and proteins); and the desire to accelerate analyses and obtain information (allowing for retrospective data mining).

    A selection of compounds, new challenges, and methods currently employed in doping control laboratories will be presented to the audience including, for example: new anabolic agents referred to as selective androgen receptor modulators (SARMs); insulins; so-called "releasing peptides" that stimulate the endogenous production of natural hormones; and ways of manipulating drug tests.

  • Introduction to Liquid Chromatography Recorded: Jan 19 2010 51 mins
    Professor Peter Schoenmakers
    In this webinar, Professor Peter Schoenmakers will provide insight into the various LC techniques, including:

    * An overall perspective of current usage and applications of the various techniques.
    * A description of how the techniques developed, starting from paper chromatography up-to current "high tech" two-dimensional separations.
    * A more detailed focus on the concept of various methods.

    Often portrayed more as magic than science, popular television series such as CSI have aroused great interest in analytical chemistry. Forensic science relies on separation science.

    Peter Schoenmakers' webinar will also, in a light-hearted manner, put LC methods into the correct perspective for forensic science.
  • Introduction to Gas Chromatography Recorded: Oct 28 2009 52 mins
    Professor Harold McNair
    The first activity in the Year of Education is a series of free educational webinars, run in conjunction by separationsNOW and Chromedia. In the first webinar, Professor Harold McNair gives an interactive lecture on the basics of gas chromatography.

    This first webinar is intended for persons who:

    * Use chromatography and would like to revisit the basics of GC.
    * Have a little knowledge and would like to learn more!

    Some knowledge of general and organic chemistry is assumed. The webinar should prove useful to technicians, students, graduate students, PhDs and even professors planning to work with GC.

    Topics to be discussed are:

    * Definitions of GC
    * Separation principles
    * Advantages and limitations of GC
    * Basic instrumental components of a GC
    * Capillary columns
    * Three detectors: FID,TCD and ECD
brought to you by separationsNOW.com (Wiley-Blackwell) and Chromedia
The Year of Education came about through discussions between 3 professors who actively teach chromatography:

* Professor Harold McNair, Virginia Tech, Blacksburg, USA
* Professor Pat Sandra, University of Ghent, Belgium
* Professor Peter Schoenmakers, University of Amsterdam, Netherlands

"The first activity is a free webinar on gas chromatography, followed by a number of other activities, more webinars, online short courses, tutorials, instruction videos and much more! 2010 will be a year full of activities.

Many experts will be involved, from university and industry. We believe all chromatographers should actively take part in this: in teaching, telling their employees and students to take courses. This is a chance they should not miss!"
